Detailed Implementation

[0008] like Figures 1-4 As shown, this utility model discloses an aerobic fermentation ammonia removal device suitable for livestock and poultry manure. The main body is an ammonia removal tank 7, which is a vertical tank made of stainless steel and is fixedly installed on the ground.

[0009] An observation port 8 is provided in the middle of the side wall of the ammonia removal tank 7. The observation port 8 consists of a flange welded to the side wall and a transparent acrylic plate, which can be used to observe the state inside the ammonia removal tank 7.

[0010] The lower part of the side wall of the ammonia removal tank 7 is provided with a water inlet 9, which is connected to a water injection pipe (not shown in the figure). Liquid can be injected into the ammonia removal tank 7 through the water inlet 9.

[0011] The bottom of the side wall of the ammonia removal tank 7 is provided with a drain port 10, which is connected to a liquid collection device (not shown in the figure). By opening the drain port 10, the liquid in the ammonia removal tank 7 can be discharged to the liquid collection device.

[0012] A spray water pump 1 is fixedly installed on the ground on one side of the ammonia removal tank 7. A suction pipe 14 is fixedly installed at the inlet of the spray water pump 1, penetrating the tank wall of the ammonia removal tank 7 and bending vertically downward at the end, extending below the liquid level inside the ammonia removal tank 7. A spray pipe 2 is vertically installed at the outlet of the spray water pump 1, horizontally penetrating the tank wall from the top of the ammonia removal tank 7. A downward-opening spray head 201 is provided at the end of the spray pipe 2. When the spray water pump 1 is started, the liquid in the ammonia removal tank 7 can be drawn through the suction pipe 14. The liquid flows through the spray water pump 1 and the spray pipe 2, and is then sprayed into the ammonia removal tank 7 by the spray head 201.

[0013] like Figure 5 As shown, an air inlet pipe 15 is provided on the lower part of the side wall of the ammonia removal tank 7. One end of the air inlet pipe 15 leads to the reactor (such as a livestock and poultry manure fermentation tank, not shown in the figure), and the other end extends into the interior of the ammonia removal tank 7. It is an upward-curving "L" shape, as shown in the figure. Figure 7 As shown, an air inlet pipe cover 1502 is provided at the end of the air inlet pipe 15. The air inlet pipe cover 1502 is installed on the end outlet of the air inlet pipe 15 through the air inlet pipe column 1501, which can prevent the sprayed liquid from entering the air inlet pipe 15.

[0014] like Figure 6 As shown, a sensor mounting bracket 11 is fixedly installed on the lower part of the inner wall of the ammonia removal tank 7. A smart ammonia nitrogen concentration sensor 12 and a liquid level sensor 13 are installed on the sensor mounting bracket 11. The smart ammonia nitrogen concentration sensor 12 can detect the ammonia concentration of the liquid in the ammonia removal tank 7, and the liquid level sensor 13 can detect the liquid level height in the ammonia removal tank 7.

[0015] like Figure 7 As shown, the top of the ammonia removal tank 7 is equipped with a blower base 6, and a blower 5 is fixedly installed on the blower base 6. The air inlet of the blower 5 is connected to a suction pipe 3, and the other end of the suction pipe 3 is connected from the top of the ammonia removal tank 7 to the inside of the tank body. The air outlet of the blower 5 is connected to a gas transmission pipe 4, and the gas transmission pipe 4 is connected to a gas collection device (not shown in the figure).

[0016] The intelligent ammonia nitrogen concentration sensor 12 can control the operation of the following components: Open the drain port 10; Shutting down fan 5; Close the intake manifold 15; Shut down spray pump 1.

[0017] The liquid level sensor 13 can control the operation of the following components: Opening and closing of water inlet 9; Close drain port 10; The air intake pipe 15 is opened.

[0018] An interlock switch is provided on the air inlet pipe 15. When the air inlet pipe 15 is opened, the spray water pump 1 and the fan 5 will be started automatically.

[0019] like Figure 8 and Figure 9 As shown, this utility model discloses an aerobic fermentation ammonia removal device suitable for livestock and poultry manure, the working principle of which is as follows: Close the drain port 10, open the water inlet 9, and inject water or other liquids that can dissolve ammonia into the ammonia removal tank 7. When the liquid level rises to the upper limit position of the float of the level sensor 13, the level sensor 13 sends a signal, and the water inlet 9 automatically closes.

[0020] When the inlet pipe 15 is opened, the ammonia-containing gas generated by the reactor enters the ammonia removal tank 7. At this time, the spray water pump 1 and the blower 5 start simultaneously. The spray water pump 1 draws liquid from the bottom of the ammonia removal tank 7 through the suction pipe 14. The liquid flows through the spray pipe 2 and is sprayed out by the spray head 201. The sprayed liquid comes into contact with the gas in the ammonia removal tank 7, dissolves the ammonia in the gas, falls to the bottom of the tank, and is drawn out again by the spray water pump 1, and the cycle repeats. The blower 5 extracts the gas after ammonia removal, and after passing through the suction pipe 3 and the gas delivery pipe 4 into the gas collection device, the blower 5 continues to extract the ammonia-containing gas from the reactor into the ammonia removal tank 7.

[0021] The intelligent ammonia nitrogen concentration sensor 12 detects the ammonia concentration in the liquid at the bottom of the ammonia removal tank 7. When the ammonia concentration reaches the saturation concentration, it means that the liquid can no longer dissolve more ammonia. The intelligent ammonia nitrogen concentration sensor 12 sends a signal to control the fan 5 to shut down, the spray water pump 1 to stop working, the air inlet pipe 15 to close, and the drain port 10 to open, so that the liquid in the ammonia removal tank 7 is discharged to the liquid collection device.

[0022] The liquid level sensor 13 detects the liquid level in the ammonia removal tank 7. When the liquid level drops to the lowest point, it sends a signal to control the drain port 10 to close, stopping the discharge of liquid, and the water inlet 9 to open, injecting liquid that has not been dissolved in ammonia into the tank.

[0023] When the liquid level rises to its highest point, the liquid level sensor 13 sends a signal to control the water inlet 9 to close and the air inlet pipe 15 to open, at which point the ammonia removal process can continue.

[0024] By using the intelligent ammonia nitrogen concentration sensor 12 and liquid level sensor 13 in conjunction with the control device to control the actions of various components, this utility model realizes the automation of the ammonia removal process, improves the ammonia removal efficiency, and saves labor costs.
